Chrysanthemum plant named ‘Grace Time Pink’

Abstract

A new variety of Chrysanthemum plant named ‘Grace Time Pink,’ having a good uniform canopy of purple quill single flowers with a light green disc. The new variety has a medium vigor, free branching, uniform spreading habit and good foliage presentation.

Description

Latin name of the genus and species: Botanical classification: Chrysanthemum morifolium.

Variety denomination: The new Chrysanthemum variety denomination is ‘Grace Time Pink.’

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Chrysanthemum botanically known as Chrysanthemum morifolium, and referred to by the cultivar name ‘Grace Time Pink.’ ‘Grace Time Pink,’ identified as 20911-0A, was discovered as a whole plant mutation grown in a controlled cultivated planting of the variety ‘Grace Time’ (unpatented seedling). The new variety ‘Grace Time Pink’ has been asexually reproduced by vegetative cuttings in Chichester, West Sussex, United Kingdom and the distinguishing characteristics are retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

‘Grace Time Pink’ is a pot type of Chrysanthemum plant variety having purple quill single flowers.

Comparison with Parent

Plants of the new Chrysanthemum variety ‘Grace Time Pink’ are similar to the parent ‘Grace Time’ in plant habitat and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Grace Time Pink’ compared to plants of the parent ‘Grace Time’ in the following characteristics.

• • 1. The new variety ‘Grace Time Pink’ produces purple quill single flowers whereas the parent ‘Grace Time’ also produces purple quill single flowers.
  • 2. Plants of the new variety ‘Grace Time Pink’ have smaller and shorter inflorescence than plants of the parent ‘Grace Time.’
  • 3. Plants of the new variety ‘Grace Time Pink’ have a slower response than the plants of the parent ‘Grace Time.’
  • 4. Plants of the new variety ‘Grace Time Pink’ have a shorter vigor than the plants of the parent ‘Grace Time.’

Comparison with Other Varieties

Plants of the new Chrysanthemum variety ‘Grace Time Pink’ are dissimilar to the variety ‘Scott’ (U.S. Plant Pat. No. 14,155) in plant habitat and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Grace Time Pink’ differed from plants of the ‘Scott’ variety in the following characteristics.

• • 1. The new variety ‘Grace Time Pink’ produces purple quill single flowers whereas ‘Scott’ produces purple spoon tip single flowers.
  • 2. Plants of the new variety ‘Grace Time Pink’ have larger and taller inflorescence than ‘Scott.’

DETAILED BOTANICAL DESCRIPTION

The following description of the new Chrysanthemum variety ‘Grace Time Pink’ is of plants grown in a greenhouse in Chichester, West Sussex, United Kingdom in the month of June. The cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment such as temperature, length of day and light intensity, without any variance in genotype. The commercial classification of the new variety is a pot Chrysanthemum.

Plants of the new variety have been grown successfully under temperature conditions averaging about 19° C. at night and about 17° C. to 24° C. during the day under light conditions of about 5,000 to 6,000 foot candles. The plants respond well to the use of growth retardant, such as one B9 treatment at about 2 gm per liter. To produce a commercial product the plants may be pinched once with the center bud removed. The typical container size for commercial growth is 1 liter. It has been observed that the shelf life of the new variety is about 21 days with a response time of about 8 weeks. The new variety is suitable for growth in a temperature range of 15° C. to 25° C.

The new variety may be produced as a spray. The following description is with respect to a plant produced as pot. In the description of this new Chrysanthemum variety, color values have been taken from The Royal Horticultural Society Colour Chart (R.H.S.C.C.).
